MACHINE Fon THE sINrnRING or ona AND 'rnnmxn Application filed November 16, 1926, SeriaI No. 148,739, and in Sweden August 1, 1926. vv

My invention relates to machine intended for the sintering (agglomerating) l of dressed ore, as for instancevslime landthev like, with the aid of the known process, according to which avcurrent of air is ycause/d to pass through a mixture of ore and a suitable fuel, as for instance coal dustand the like, which is ignited at its surface by'inean's of oil, a gas'flame, `avglowing fuel, or the IH like.

The invention is illustrated diagrammatically and by way of example onthe accompanying drawing on which Figure lis a plan of a sintering or agglomerating ma- 'W chine designed according to this invention, and Figure 2 is a vertical section through the same in the plane X-X of Fig. 1, this Figure (2) being drawn to an enlarged scale and showing only one half of the machine. v 2" On the drawing, o denotes a circular frame carrying a plurality of sintering pans a arranged in a circle. The frame 'v with its pans a can be turned around a centrally4 i arranged suction vessel Z). Each pan is procated below the grate is of hopper-like shape, and from the centre of this portion extends a suction pipe 't connected at its other end with a horizontal branch pipe (Z v.

3" of a Vertical casing c secured to a plate closmg the vessel b. i

In the sintering or agglomeratmg ma-V chines of the type in question as hitherto designed the branch cl and the end of the tube t were connected turnably with each other by means of a suitably designed coupling permitting tipping and invertingthe respective pan in order to empty it in this way. Experience has, however, shown that this 40 construction does not render possible maintaining the proper 'shape of the panV and has,

therefore, proved unsuited for practical employment. i

Now, according to the present invention the connection between the each'pan and the branchd has been rendered disconnectible, in such a manner,'that the tipping axis of each pan forms a larger or smaller angle, preferably a` rectangle, 5o with the tube a-Xis at the place of connection. It has been found that a connection of this kind can be kept perfectly tight even if the shape of the pan has undergone considerable changes, and it is now rendered vpossible to make the pans of sheet-metal,

tively to it by means of a stufling a vided with a grate'fw; the pan portion lo-' the pans radially inwards with the' respect suction pipe of' whereas formerly cast iron, if not Cast Steel, wasnecessary.` Besides that ad'vantage, another is attained by the simple'radial a rrangement Iof the stationary tube branch d, and resides therein that the tipping takes places about a tangential aXis whereby it isprendered possible that the` operater who stands upon the neighboring stationary platform can tilt each pan with Aone of his 'cet.

lThe most exterior part Z of the. branch d ispreferably shiftable withy respect to the other'part. proper), and tightened relaboX m.

Preferably a packing' n'is inserted into the joints betweenV the branch portion Z and'the suction pipe t, and'a lever s is provided by means of whichthe branch portion Z can be withdrawn from the tube tr V i The casings c are valve casings, therebeing a valve provided for each suction pipe and located between it and the common suction vessel b.v This vessel is rotatory on the top of a stationary suction pipe p provided with a stufing box r for tightening it.
